8.2 Testing the Touchpoint Plus System

8.2.1 Introduction

The Touchpoint Plus system has two test modes available, which together enable a full test of the system.
The test modes are:
•
Field Inputs Test – tests all input channel devices without affecting any outputs.
•
Cause and Effect Test – forces the Touchpoint Plus input channels to specific states to test that the
correct relay output channels are activated.
The Touchpoint Plus system is not operational while in Test Mode, and all field device inputs will be ignored.
Ensure that alternative safety arrangements are maintained during test, and ensure that Test Mode is exited as
Test output conditions will be simulated and relays will be activated during the Cause and Effect Test.
Ensure that relay activated output systems (i.e. emergency deluge / sirens etc.) are isolated before starting the
When any of the test modes is active, the System Failure relay will activate to indicate that the safety function
of the system is not operating. A Fault will be shown as an Active Event on the User Interface.
Once a test mode is active, the system will remain in test mode until the test is exited. The only exception is in
the case of a power cycle of the Touchpoint Plus system, when it will restart in normal mode.
All events generated while the system is in test mode will be logged in the event history. Therefore a record of
the testing can be generated once it is complete (see Normal Operation, Generate Reports).

8.2.2 Field Inputs Test

To carry out the Field Inputs Test:
1) Login as an Administrator or Engineer.
2) Set 'Inhibit Input Channels'.
3) Supply test gas for the input channels.
4) System will display the gas reading and inhibit state.
5) Pre-configured Inhibit outputs (relays and mA output channels with output inhibit state) will be triggered
but all alarm outputs are inhibited.
Maintenance
soon as testing is completed.
Ensure that the system is returned to normal operation once testing is completed.
